  Overview: This host has critical security update missing according to
  Microsoft Bulletin MS08-071.

  Vulnerability Insight:
  The flaw caused due to,
  - overflow error in GDI when processing headers in Windows Metafile (WMF)
    files.
  - an error exists in the the way the GDI handles file size parameters in
    WMF files.

  Impact:
  Successful exploitation could execute arbitrary code on the remote system
  and cause heap based buffer overflow via a specially crafted WMF file.

  Impact Level: System

  Affected Software/OS: Microsoft Windows 2K/XP/2003

  Fix:
  Run Windows Update and update the listed hotfixes or download and
  update mentioned hotfixes in the advisory from the below link.
